Question

We consider the radiation emitted by the human body. Which of the following statements is true ? (A) The radiation is emitted during the summers and absorbed during the winters (B) The radiation emitted lies in the ultraviolet region and hence is not visible (C) The radiation emitted is in the infrared region (D) The radiation is emitted only during the day

Tardigrade Admin · Accepted Answer

The heat radiation emitted by the human body is the infrared radiation. Their wavelength is of the order of

7.9 \times 1 0^{- 7} m

to

1 0^{- 3} m

which is of cource the range of infrared region.
Hence, human body emits radiation in infrared region.
